To an wlamiamay concave:

Be it kno'wnbthat weierra Kmaend Fommsr- J.- Coecn, beth'o'f:Rochester', in the county of Monroe and State of New "York, have'invented certain new and use-r111 Imp rovem'ents irt Treaetle'Mechanism; and We do hereby declare the fol'low'in to lie -a full,clear, and exact description otihe same, ref erence being had tothe-accom anyin draw ings, forming a part of this sacrifice engand tothe reference-numerals marked thereon.

Our invention relatesgto treadle mechanisms of the type generallyemployed in conjunction with various types of apparatus designed forfoot control, s uch'as ironing machines, presses'anH- the liliey'an'cllit has for its particular perms-teasers a' simplifiedconstruction that permits a single tftdldto" eyed are acacia capacity,-to effect operation of the machine and tore-' store the parts after theoperation to their normal position. A further object of the invention isto lessen the cost of construction by eliminating one treadle from theusual double treadle arrangement, in which one treadle is employed foroperating and a sec ond treadle for releasing or restoring the parts. Afurther advantage of the improvement is found in the reduction of laborwhich it causes, since the operator does not need to change the positionof the foot which is used to control the treadle, as the latter isoperated from different positions and in varying relations, in order toeffect the desired movements of the other parts of the mechanism. Tothese and other ends the invention resides in certain improvements andcombinations of parts all as will be hereinafter more fully described,the novel teatures being pointed out in the claims at the end of thespecification.

In the drawings:

Figure 1 is a side elevation of an ironing machine with the inventionapplied, and showing the position of the parts when the machine is in.its operating position;

Fig. 2 is an elevation of the treadle mechanism, showing the position ofthe operating lever and other parts after the initial releasing movementof the controlling member or treadle; u

Fig. 3 is a similar view after the parts are completely restored tonormal position;

Fig 4 1s aseotional view in a horizontal p1ar1e" showing the tre'adlemechanism in P Similar reference characters throughout the severalfigures indicate i the same parts.

The scope of the "invention is net-wh te limited in any sense to theparticular application or" forrn' of mechanism that isfset forth in thepresent case, asi t 'majti be otherwrse appliedin connection with anmeehw nism involving operating leverarranged for movement in oppositedirections and delineated with acontrolling member'- for-er fe'ctingitsopposite movements. "In tlie arr-angemenit shown, which is" illustrativeeta referredconstruction, we employ a base 1 and a vertical f-rame 2 cn'whi'ch is mounted} a stationary ironingand pr'e'ssing member or chest 3adapted to be heated by a suitable ame medium that is -s=ap u-ied--tnioagawne 'pip e's i. Arranged for cooperation with the heated member 3is a vertically movable bed that is carried upon a movable frame whichis connected for operation to a toggle joint consisting of links 5 and6, the latter forming part of an operating lever 7 which is pivotallymounted on a post 8 supported in the base 1.

The operating lever 7 has pivoted at its outer end a controlling memberor treadle 10 which is provided with a downwardly projecting lug 11 at apoint near its connection with the lever 7, and arranged to engage thebase fiange 12 and constitute a fulcrum in the manner shown in Fig. 1.The operating lever 7 carries an overhanging portion 13 which engages anextension 14 formed on the controlling member in the manner shown inFig. 3 to form a stop, while 15 is an upstanding portion or toe uard atthe front end of the treadle 10. he link 6 preferably carries a spring16 which acts as a butter and en ages the abutment 17 to preventexcessive s ock, as the parts are returned to thelr normal position,shown in Fig 3.

he operation of the device may be de scribed briefly as follows: Withthe parts in the position illustrated in Fi 3, in order to effectoperation of the mac ine the outer end of the controlling member 10 isengaged and depressed, and by reason of the engagement of the extension14 with the portion 13, the operating lever is caused to movedownwardly, and the controlling member moves bodily with it. The leverswin s about its axis and st'raightens the togg e joint to bring theironing members into ironmg relation. The parts are then in the positlonshown in Fig. 1. To release the mechanism and restore the parts tonormal position, the inner end of the controlling member 10 isdepressed, rocking the treadle on the projection 11 as a fulcrum andthereby causing the outer end of the operating lever to move slightly inan upward direction in the manner showninF-ig. 2, until the toggle jointis broken. The weight of the parts is then sufiicient to complete therestoring operation, moving the operating lever upwardly until itassumes the position shown in Fig. 3, after which the parts are readyfor a second operation. It will be seen that the controlling member isthus moved about separate or independent fulcrums, afiorded by pivotalaxis 8 and projection 11, to elfect opposite movements of the lever, andmovement of the treadl'e about axis 8 is, in the present instance,caused by the overhanging ortion 13 arranged on the opposite-.side ofever 7 from projection 11, and engaging-extension 14 to cause .thecontrolling. member to move bodily with the lever.

We claim as our invention:

1. The combination with an operating lever, of a controlling memberpivoted to the operating lever, a stop on the lever which limits therelative movement of the controlling member in one direction, and aprojection on the controlling member which serves as a fulcrum when itis moved in the opposite direction relatively to the lever.

2. The combination with an operating lever, of a controlling memberpivoted thereon, and independent fulcrums about which the controllingmember is operable in order JOHN KANE. FORREST J. COUCH.
